Washington (CNN) - Ever present but rarely so public, the rift between conservative and moderate Republicans over policy and tactics was on full display Thursday ahead of a House vote on the compromise federal budget worked out with Democrats.

House Speaker John Boehner escalated his criticism of conservative groups opposed to the budget deal, saying they lost credibility by rejecting the plan before it was announced and blaming them for pushing GOP legislators into the politically disastrous government shutdown in October.

Washington (CNN) - Republican disarray over taxes forced House Speaker John Boehner to drop his alternative proposal to a fiscal cliff deal, leaving the negotiations in limbo Friday - 11 days before automatic tax increases on everyone.

Boehner said at a news conference Friday morning that his Republican colleagues refused to back his plan because of what he called unfounded fears of being blamed for a tax increase.
